hi<br />I have a 1991 Bayliner with a 120 hp force L-Drive. the lower unit was drug on the pavement by the prevous owner and ground a nice hole in the nose of the gear case. It didn't damage the gears or shaft other then to jam them with debris My question , can the case be welded or is it pot alum and if it can't do you think if i drilled and threaded holes in case for screws and sealed and capped it would it hold? the surface edges are nice and flat(couldn't have been a highway around here where it was drug)with plenty of meat for screws.<br />thank you for your time<br />dennis
